IMPROVEMENT- m WASH-BOILERS.

Specification forming part of Letters Patent No. 132,979, dated November12, 1872.

El Dorado, in the county of Union and State of Arkansas, have invented anew and Improved Wash-Boiler, of which the followingis a specification:

My invention consists of a combination of wire-coils with the nozzles,through which the water is discharged into the space containing theclothes from the conductors, through which the hot water and steam areforced up from the heating-chamber below, which said coils maintainchannels between the clothes which are packed around them, so as tofacilitate-the circulation of the steam and water, and equalize andincrease their effectiveness. The invention also consists of thearrangement of the check-valves and their adjuncts on a removable coverof the hole in the false bottom to facilitate the cleaning of theheating-chamber.

Figure 1 is a longitudinal sectional elevation of my improvedwash-boiler, and Fig. 2 is a horizontal section taken on the line y y ofFig. 1.

Similar letters of reference indicate correspondin g parts.

A is a wash-boiler, which maybe of any approved construction andarrangement for causing the hot water and steam to flow up from aheating-chamber, B, at the bottom through channels or conductors O todischarge through nozzles or passages D of any kind into the space Eamong the clothes. I propose to combine coiled wires F with thesenozzles or passages D in the manner indicated in the drawing or in anyapproved way, so that they may be packed between or in the clothes whenthey are put in said space E, so that they will maintain channels forthe water to circulate more freely and with better eflect among theclothes than when packed in the ordinary way without such devices, asthey obstruct the escape of the water from the said nozzles or holes,and prevent it from escaping between them. I prefer to attach the saidcoils to the nozzles, or to the walls of conductors 0, coincident withthe openings, but they may be used separately with good results, beinglaid on the clothes as they are packed in the boiler and taken out withthem. I may use perforated metal tubes instead of the wire-coils, but Iprefer the latter. I propose to have win g-valves G for letting thewater into the chamber B and retaining it to force it up through thepassages O, said valves being hinged to a plate, H, which is laid on thefalse bottom I over a hole, through which the valves work downward, sothat it can be readily removed for cleaning out the heating-chamber. Aguard, K, is attached to the under side of this plate to limit theopening of the valves, and another guard, L, is placed 011 the upperside to prevent the clothes from choking up the passage.

Having thus described iny invention, I claim as new and desire to secureby Letters Patent 1. The combination of the wire-coils F or theirequivalent, with the nozzles or other discharge devices of the verticalpassages 0, substantially as specified.

2. The wing-valves G, attached to a removable cover, H, of the falsebottom I, having the guard K and L, substantially as specified.
